Yeah, with a move from gas for cooking to induction (or similar) a lot of people have to adapt their fuse box and get a 3 phase installed. Right now in some regions there's a several month waiting list though 
Why would you need 3 phase for induction cooktop? You just need 220v for that, which is L+L (split phase) for U.S and N+L for the majority of the world, probably for the car charger?
So most homes around the globe will have two wires, N and L, where the voltage between the two is 220v to 240v.
Sorry, slow response. Not sure about the exact technical reasons, but as it was explained to me by an electrician, is that there is a lot more electric usage these days, so for over a decade they do newly build houses with 3 phase to be "prepared". By itself 2 phase would be working for many induction stoves, but (if I'm not mistaken) it's 5 or more hobs and/or downward extraction of air, it can go over the specs for 2 phase.
As he explained it would in case of washer+dryer+dishwasher+induction potentially be too much, and that's not taking into account car chargers.
